I've got a number of audio recordings which I can't play back. It appears to be a case of a missing codec, but I can't locate the codec in question.

VLC will not play the files. ffmpeg gives the error Unsupported codec (id=0) for input stream 0.

This is the output from MediaInfo.

Can anyone help?

Say I have 3 HDDs with the following write speeds: HDD1 with 50 mb/s, HDD2 with 22 mb/s and HDD3 with 45 mb/s. Combined… >>> More
